MITER-BOX.

Application led May 12, 1909. Serial No. 495,400.

Specification of Letters Patent.

Patented Mar. 11, 1911.

To all whom 'it may concern:

Be it known that I, FRANK Parr, citizen of the United States, residingin the city and county of San Francisco and State of California, haveinvented new and useful Improvements in Miter-Boxes, of which thefollowing is a specification.

My invention relates to carpenters7 miter boxes.

The object of the present invention is to provide a simple, cheap,practical miter box which will enable carpenters to use their ordinarysaws with it; which will have the various parts coming in contact withthe saw teeth formed of wood, so there will be no danger of damage tothe saw; and in which these various parts which are subjcct to wear willbe readily renewable.

The invention consists of the parts and the construction and combinationof -parts as hereinafter more fully described and. claimed, havingreference to the accompanying drawings, in which- Figure 1 is a plan.Fig. 2 is an end view, partly in section. Fig. 3 is a perspective of theouter end of the saw carrier.

In the embodiment of the invention I employ a wooden bottom A and a rearvertical wooden side 2 suitably secured to the frame 3 having the legsf1, and which frame is preferably made up of channel or malleable iron.

6 is a saw carrier bar pivoted at 7 at one side and between the ends andon the under side of the bottom; a wearing plate 8 be ing secured to thebottom andvinterposed between the latter and the carrier bar 6.

9 is a segmental rack secured at its ends to the under side of thebottom A, and with the front curved portion dropped down underneath thecarrier bar 6, so that the latter works over the rack 9; the rack 9being concentric with the pivot 7. The carrier bar extends acrossunderneath the bottom A and over the projecting dropped front of therack 9, and is adapted to be locked at suitable point in thecircumference of the rack by suitable means, as the spring actuatedlatch 10 engaging suitable notches 11 inthe periphery of the rack.

Fach end of the carrier bar 6 is provided with two spaced upright metalpins 12 adapted to form dowel members seating in sockets incorresponding square wood posts 13, each pair of posts being separatedjust the width of the saw blade, and the two pairs of posts adapted tohave the slots formed between them aline and form suit able guides forthe saw. The posts are prevented from turning by suitable means, as therigid plate 141 which is approximatelv the same thickness as the sawblade; one of these stop plates 14C being carried at each end of therack bar G and between its respective pair of pins 12.

15 is a short wooden post driven into a hole in each end of the carrierbar 6, or otherwise suitably secured thereto, these pins 15 being placedin line with the slots between the guide posts 13 and adapted to preventthe saw teeth from striking any of the metal parts of the device. Thetops of these pins 15 do not extend above the level of the top of thebottom A, so as to allow the saw to saw clear through the timbersupported in the miter box.

By lift-ing the latch 10 and turning the carrier bar 6, then releasingthe latch, the box can be set to cut any desired angle. The

vfour wooden uprights or saw guides 18 can be raised up on their pinsupports 12 and then turned around so that all four sides can be usedbefore they will have to be renewed. Manifestly the back 3 has asuitable slot to allow the saw to Work through and permit the latterbeing set at the various angles desired.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A miter box having a bottom and a back portion, anda pivoted saw carrier thereon, said saw carrier having renewable woodposts at its ends forming saw guides, said posts being square incross-section and removably mounted on fixed pins on the saw carrier,with stop means on the saw carrier to prevent the turning of the posts,and renewable wood stop pins carried by the saw carrier and in line withthe slots between the saw guides.

2. A miter box having a bottom and a back portion, and a pivoted sawcarrier thereon, said saw carrier having renewable wood posts at itsends forming saw guides, said posts being square in cross-section andremovably mounted on fixed pins on the saw carrier, with stop means onthe saw carrier .to prevent the turning of the posts, renewable woodstop pins carried by the saw carn rier and in line with the slotsbetween the saw guides, said saw carrier pivoted to the under side ofthe bottom and near one edge In testimony whereof I have hereunto setthereof and extending across the bottom, a my hat-nd in presence of twosubscribing Witsegmental rack concentric With the pivot vof DGSSSS- thesaw carrier and secured to the bottom FRANK PAFF. and having :L frontportion dropped down l Witnesses: beneath the carrier, and means forlocking i CHARLES A. PENFIELD, the carrier to the rack at any desiredangle. l CHARLES EDELMAN.
